According to some embodiments of the present disclosure, two or more processing components (or processing cores) are configured to access data stored in one memory unit (or cache memory), and thus the memory capacity of the memory unit can be distributed according to the computing loading of the two or more components (or processing cores). Therefore, the memory capacity efficiency can be significantly increased.

In addition, according to some embodiments of the present disclosure, the memory unit bonded to two or more processing components (or processing cores) can provide additional memory capacity for the processing component (or the processing core) in addition to the built-in memory of the processing component. Therefore, the memory unit shared by two or more processing components (or processing cores) can not only provide additional memory capacity but also increase memory capacity efficiency.

Moreover, according to some embodiments of the present disclosure, the memory unit is hybrid-bonded to the active surface of the processing component, and/or the memory unit is bonded to the active surface of the processing component through a solder-free joint or a non-solder joint. Therefore, the resistance of the transmission path between the memory unit and the processing component is relatively low, which is advantageous to improving the access rate for the processing component.

In cases where a memory unit is integrated into a processing component during manufacture, the process for forming processing elements of the processing component demands increased precision (e.g., a relatively high processing precision), and thus the memory unit formed together with the processing elements also demands increased precision (e.g., a relatively high processing precision), which can increase process complexity as well as costs In contrast, according to some embodiments of the present disclosure, a wafer node of the processing component (or the processing core) is less than or smaller than a wafer node of the memory unit, and the memory unit is manufactured separately from the processing component and then bonded to the active surface of the processing component. Therefore, the precision required for manufacturing the memory unit is less than that for manufacturing the processing component (or the processing core), and processes requiring different levels of processing precision are performed separately, simplifying overall process and reducing costs.

Thus, less processing precision is required to manufacture the active interposer than for manufacturing the processing component (or the processing core), processes requiring different levels of processing precision are performed separately, overall manufacturing process is simplified, and costs are reduced.

In addition, according to some embodiments of the present disclosure, the connection structure 40 may be an I/O element divided from or originating from a monolithic processing unit and configured to replace an I/O element presumably integrated in the processing component (or the processing core).

As used herein, the terms “approximately,” “substantially,” “substantial” and “about” are used to describe and account for small variations. When used in conjunction with an event or circumstance, the terms can refer to instances in which the event or circumstance occurs precisely as well as instances in which the event or circumstance occurs to a close approximation. For example, when used in conjunction with a numerical value, the terms can refer to a range of variation less than or equal to ±10% of said numerical value, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. For example, two numerical values can be deemed to be “substantially” or “about” the same if a difference between the values is less than or equal to ±10% of an average of the values, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. For example, “substantially” parallel can refer to a range of angular variation relative to 0° that is less than or equal to ±10°, such as less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°. For example, “substantially” perpendicular can refer to a range of angular variation relative to 90° that is less than or equal to ±10°, such as less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°.

Two surfaces can be deemed to be coplanar or substantially coplanar if a displacement between the two surfaces is no greater than 5 μm, no greater than 2 μm, no greater than 1 μm, or no greater than 0.5 μm.

As used herein, the terms “conductive,” “electrically conductive” and “electrical conductivity” refer to an ability to transport an electric current. Electrically conductive materials typically indicate those materials that exhibit little or no opposition to the flow of an electric current. One measure of electrical conductivity is Siemens per meter (S/m). Typically, an electrically conductive material is one having a conductivity greater than approximately 104 S/m, such as at least 105 S/m or at least 106 S/m. The electrical conductivity of a material can sometimes vary with temperature. Unless otherwise specified, the electrical conductivity of a material is measured at room temperature.

As used herein, the singular terms “a,” “an,” and “the” may include plural referents unless the context clearly dictates otherwise. In the description of some embodiments, a component provided “on” or “over” another component can encompass cases where the former component is directly on (e.g., in physical contact with) the latter component, as well as cases where one or more intervening components are located between the former component and the latter component. In the description of some embodiments, a component provided “under” or “below” another component can encompass cases where the former component is directly below (e.g., in physical contact with) the latter component, as well as cases where one or more intervening components are located between the former component and the latter component.

While the present disclosure has been described and illustrated with reference to specific embodiments thereof, these descriptions and illustrations do not limit the present disclosure. It can be clearly understood by those skilled in the art that various changes may be made, and equivalent components may be substituted within the embodiments without departing from the true spirit and scope of the present disclosure as defined by the appended claims. The illustrations may not necessarily be drawn to scale. There may be distinctions between the artistic renditions in the present disclosure and the actual apparatus, due to variables in manufacturing processes and the like. There may be other embodiments of the present disclosure which are not specifically illustrated. The specification and drawings are to be regarded as illustrative rather than restrictive. Modifications may be made to adapt a particular situation, material, composition of matter, method, or process to the objective, spirit and scope of the present disclosure. All such modifications are intended to be within the scope of the claims appended hereto. While the methods disclosed herein have been described with reference to particular operations performed in a particular order, it can be understood that these operations may be combined, sub-divided, or re-ordered to form an equivalent method without departing from the teachings of the present disclosure. Therefore, unless specifically indicated herein, the order and grouping of the operations are not limitations of the present disclosure.
